APPARATUS FOR WAXING PAPER AND OTHER MATERIAL.

SPECIFICATION forming part of Letters Patent No. 360,373, dated March 29, 1887.

Application filed November 2, 1886. Serial No. 217,523. (No model.) V

To all whom it may concern.-

Be it known that 1, STEPHEN M. GHEsTEn, of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Apparatus for \Vaxing Paper and other Material; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in apparatus for waxing paper and other materla The object is to provide simple and convenient means for impregnating paper and other material with wax and giving its surface a glossy finished appearance without the employment of strippingpads and calendering rolls or surfaces, commonly employed for the purpose.

A further object is to provide means for conducting the vapor of the volatile solvent in ,which the wax is dissolved to a condenser.

With these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical longitudinal section of the apparatus with parts in adjustment as in use. Fig. 2 is a similar view with cover elevated out of contact with tank, and Fig. 3 is a plan view with top or cover removed. Figs. 4, 5, 6, and 7 represent, respectively, a vertical, longitudinal, and cross section of a modification.

A represents the body of a main tank, preferably elongated, as shown. A second or inner tank, 13, narrower and shorter than the tank A, is adapted to be set within the tank A with its top flush with the top of the tank A and leaving a narrow space, a, between the sides and one end of the tank B and the corresponding part of the tank A, and quite a wide space, 1), between the remaining end of the tank 13 and the corresponding end of the tank A. The spaces a and 1) form one continuous space around the inner tank between its walls and those of the outer tank, and are adapted to be filled with water orfother cooling-liquid.

The interior of the inner tank, 13, is sepa rated into two compartments, 0 and G, by means of a cross-partition, D, preferably lo cated nearer one of the ends of the tank than the other; and within the smaller compartment, 0, the receptacle E, for holding the supply of dissolved wax, is located.

Along one or both sides of the inner tank, B, near the inner faces of its side walls, the steam or hot-air pipes F extend, which serve to keep the wax solution at the proper temperature, and also keep the compartment 0 warmed.

G represents the cover, provided with sides and one end sufficiently high to rest 011 the bottom of the main tankA when its top is at the top of the tank, but having the end 9 of less height than the sides and opposite end, in order to allow the paper or other material to be waxed to pass between it and the bottom of the tank. width and length that its sides and ends will occupy about the middle portion of the spaces a and b when it is lowered into position in the tank A. Vhen in such position, the joints between it and the main tank become hermetically sealed by the water which occupies the spaces a and b. The cover G is provided with several pairs of depending hangers or brackets, II h h h", &c., in the present instance four, located, as shown, along the sides of and within the walls of the cover and having the paper-roll spindle K and guide-rollers 7c k", &-e., journaled in their lowerends.

The spindle K, on which the roll of paper or other material L is mounted, is conveniently inserted in the roll of paper, or has the paper wound thereon before it is placed in position in the ends of the brackets II; and to admit of its being readily adjusted and removed from the brackets, the latter are provided with open slots I, over the mouths of which buttons i are arranged to turn and lock or release the ends of the spindle, asmay be desired. The ends of the hangers or brackets Hextend down into the wax solution in the receptacle E far enough to partially or completely submerge the roll L in the solution. The ends of the brackets h h, 820., extend down to within a short distance of the bottom of the inner tank,

The cover G is made of such.

B, the faces of the guide-rolls journaled thereinbeing far enough from the bottom of the tank to allow the paper a free passage without liability of becoming injured by contact with any deposit which may accumulate in the tank. The end gof the tank, which projects to a joint a short distance above the bottom of the tank A, has a guide-roller journaled in ears 9 depending from its corners.

The inner tank, B, is also provided with several pairs of brackets, M m m m &c., extending from its bottom or from points above its bottom up to the top edges of its sides, or nearly so, and having guide-rollers N "/2 a 01 850., journaled therein, as shown. I

The guideroller N might be conveniently journaled in upwardly-extending ears d at the top edge of the partition D, and serve to guide the paper or other material over the partition into the compartment 0. In passing it from the compartment 0 over the end of thetank B, I find it convenient to locate a roller on each side of the end of the tank, near its upper edge, and lead the paper over the one on the inside of the tank, and thence through a slit or recess in the end of the tank, thence over the roller on the outside of the end of the tank, and thence downwardly beneath the roller in the end of the cover. Instead of this, I might,- however, journal a roller in the upper edge of the tank, as in the case of the roller N, and lead the paper over it.

The Winding-reel O is conveniently journaled in a bracket, P, secured to the end of the cover and adapted to overhang the water in the tank A, outside of the end of the tank B.

The rollers n a a 850., alternate with the rollers k k, &c., the former being near the top and the latter near the bottom of the tank B. In adjusting the paper within the apparatus the cover G is raised either by purchase or by hand, the roll L is adjusted in the hangers or brackets H, the free end of the paperis then led along over the rollers N n a, &c., and beneath the rollers k It It, as shown in Fig. 2, and attached to the'windingreel. The cover is then lowered into its position within and on the tank, the rollers 70, &c., depressing the paper between the rollers N am, 850., to points near the bottom of the tank, the roll L rotating and giving the necessary length. The pa per is thus held in position in manifold, open folds throughout the length of the compartment 0, and after leaving the compartment 0 is plunged beneath the surface of the water. A blast of hot air, dry steam, or other gaseous product adapted to volatilize and absorb the solventin which the wax is dissolved, is admitted to the compartment 0 through a pipe, Q, preferably provided with a broad mouth, q, and is led off at the diagonally-opposite corner of the chamber through an escape-pipe, R. The blast thus has access to the paper while the latter is traversing the distances up and down between the rollers 70, c, and N a, &c., completely volatilizing the solvent and preparing the wax for a sudden crystallization when plunged into the cooling-liquid. paper is exposed to the blast for a maximum length of time in a minimum space, and there is at the same time great economy 1n heat. Through the escape-pipe R the solvent is led away to a condenser of any well-known or approved construction, where it is collected for reuse, thus effecting a great saving in the cost of manufacture. The tension caused by passing the paper over the many rol 1s is found to be just what is required to give 1t the smoothness which is found desirable, and W111 not, under ordinary circumstances, be liable to tear or pull it apart.

In Figs. 4, 5, 6, and 7 the paper is led directly through the blast-chamber, it hav ng been previously more or less heated and dried in the chamber communicating with the wax solution. The cover here rests in a groove 111 the upper edge of the main tank, excepting where it plunges into the tank of water at the end.

By making the blast-chamber or dryingchamber sufficiently long and the groove in the upper edge of the main tank sufficiently deep to enable the water therein to withstand the pressure within the chambers, this device might be effective; but I do not consider it as expedient as that hereinbefore shown.

It is evident that other shapes of tanks and arrangements of rollers might be adopted,and that many slight changes might be resorted to in the forms and arrangements of the several parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
